What Knots Are Most Reliable For Ridgeline Tension?

Choosing the Right Knot

When it comes to setting up a shelter frame tarp, choosing the right knot for ridgeline tension is crucial. Both the Prusik knot and the Adjustable Round Turn and Two Half Hitches (ARTTH) are reliable options. The Prusik knot, in particular, is a popular choice due to its simplicity and adjustability. It can be easily adjusted to change the tension, making it ideal for uneven ridgelines.

Setting Up the Prusik Knot

To set up the Prusik knot, start by creating a loop in the ridgeline with a minimum size of 3-4 inches in diameter. Pass the working end of the rope through the loop and then wrap it around the ridgeline 5-7 times, depending on the length of the ridgeline and the desired tension. Finally, pass the working end through the loop again and pull it tight to secure the knot.

Using the Adjustable Round Turn and Two Half Hitches (ARTTH)

The Adjustable Round Turn and Two Half Hitches (ARTTH) is another reliable option for ridgeline tension. To set it up, start by creating a round turn with the working end of the rope around the ridgeline, leaving a 2-foot tail. Then, pass the working end through the loop and wrap it around the ridgeline 5-7 times. Finally, pass the working end through the loop again and pull it tight to secure the knot. The ARTTH can be adjusted by pulling on the tail to tighten or loosen the knot.
